The AN/PSQ-20 Enhanced Night Vision Goggle (ENVG) provides increased capability by incorporating image intensification and long-wave infrared sensors into a single, helmet-mounted passive device. The ENVG combines the visual detail in low-light conditions that is provided by image intensification with the thermal sensor’s ability to see through fog, dust, rain, sleet and other battlefield obsurants. This thermal capability, useful during the day as well as in no-light conditions, gives the ENVG a big advantage over night-vision devices equipped with I² only. The ENVG also allows Soldiers to rapidly detect and engage targets because it permits use of existing riflemounted aiming lights.
Several engineering enhancements to the ENVG improve its fit and function. For example, putting the battery pack on the rear of the helmet provides better balance and increases comfort as well as stability. The system also works with existing ballistic eye protection. In addition, the system is now more compact and easier to stow when not in use. This enhances a Soldier’s mobility.
